Patent Images
1. A crash sensor for a motor vehicle comprising:
- a housing defining a path of movement between a first and a second position;
a mass disposed in said housing for movement along said path;
biasing means for biasing said mass toward said first position;
crash indication means for indicating a crash when said mass is at said second position;
blocking means for blocking said crash indication means,said blocking means including a blocking element movable between an armed and a disarmed position; and
arming means for automatically arming said sensor by deactivating said blocking means, said arming means including an arming member detached from said housing and attached to said motor vehicle and a rotatable member extending into said housing for selectively moving said blocking member between said armed and disarmed positions when said housing is installed in the motor vehicle.

Abstract
A mechanical sensor for a passenger restraint system includes several primers for activating a gas generating component, and a trigger for setting the primers off in response to a velocity change. The sensor also includes an inertial mass for sensing the change in velocity. The sensor and the restraint system coact to arm the sensor when the sensor is inserted into the system.
